Abstract
A display device especially adapted for use in pocket-sized electronic calculators has upper and lower display stages for simultaneously displaying operands. In one form shielding device is provided in order to avoid the interference between the upper and lower display stages. In addition, a variety of intraconnections among the segments, grids and cathode filaments ensures the uniformity of display brightness among the digits.
